CASSETTE TAPES

Handling Precautions

C-120 Cassettes

C-120 cassette tapes are not recommended as they use a very thin tape base which may become tangled around the capstan or pinch roller.

Tape Slack

Before putting a tape into the deck, take up any slack with a pencil or your finger tip. This precaution prevents the tape from becoming entangled around the capstan or pinch roller.

Storage Precautions

Do not store cassette tapes in a place where they will be subject to:

Extremely high temperature or excessive moisture Excessive dust

Direct sunlight

Magnetic fields (near TV sets or speakers)

To eliminate tape slack, store your cassettes in cassette cases with hub stops

Accidental Erasure Prevention

All cassettes have erasure prevention tabs for each side. To protect valuable recordings from accidental or inadvertent erasure, remove the tab for the appropriate side with a screwdriver or another tool.

To record on a tape whose ensure prevention tabs have been removed, cover the tab holes with adhesive tape.
